So interesting much like LDN (low dose naltrexone) I had used for my pain it worked wonders! I was able to get off tramodal and other horrible pain medications that caused more issues than helped ,I felt anyways . .
There has been a huge variety of people use LDN from FM, autoimmune diseases, long covid to cancers . https://barrcenter.com/low-dose-naltrexone/. Just a jumping point to do your own research:)
Methleyne blue is another medicine that the patent ran out on, of course isn't shared or acknowledged because there is no big pharma profit.
